The IDE helps you write new code by auto-completing statements for you. When you choose a suggestion, it adds corresponding package import statements on the fly. The IDE provides built-in inspections that check your code on the fly as you type it.

The available refactorings include Rename and Extractallowing you quickly and safely change your code. It only takes one click to switch to a super method, implementation, usages, declaration, and more.

Jump to any class, file or symbol, or even any IDE action or tool window in one click. When you need more information about a symbol at the caret, use quick popups: e. Some popups are available even when you use code completion: they provide additional information about selected suggestion. In some cases the IDE can generate trivial code for you.

Create run/debug configurations for tests

If you have a recursive call inside your function, the IDE will detect it and mark it on the gutter, making your code even easier to read and understand. Every function may have more than one return and panic statements. This helps you understand more quickly how a function works. The Find Usages feature may not only find all places in the code where a symbol is used, but also group these usages by type: e. This option extends the standard syntax highlighting with unique colors for each parameter and local variable.

The editor shows parameter hints for literals and nils used as method arguments. These hints make code much more readable.

The debugger works for applications as well as for tests. If you run your code with a coverage instruction, the IDE collects the data and displays it in both the aggregated view and per statement in the Editor.

The IDE provides a dedicated interface for running and debugging tests, benchmarks and checks. The built-in Git integration lets you browse the history of changes, manage branches, merge conflicts and much more. For other version control system, similar functionality is available via corresponding plugins: Mercurial, SVN, and others. The IDE comes with a built-in terminal. Depending on your platform, you can work with command line prompt, Far, powershell, or bash.

The IDE offers a plugin that lets you connect to locally running Docker machines to manage images, containers and Docker Compose services. The support for Angular and Node.

Perhaps most important of all is the go commandthe program that automatically installs, builds, and tests Go programs using nothing more than the source code as the build specification. The release of Go 1. First, some background: What does it mean for a language to support good tooling?

goland coverage

It means that the language makes it easy to write good tools and that its ecosystem supports the construction of tools of all flavors. There are a number of properties of Go that make it suitable for tooling. For starters, Go has a regular syntax that is easy to parse.

The grammar aims to be free of special cases that require complex machinery to analyze. Where possible, Go uses lexical and syntactic constructs to make semantic properties easy to understand.

Examples include the use of upper-case letters to define exported names and the radically simplified scoping rules compared to other languages in the C tradition.

Finally, the standard library comes with production-quality packages to lex and parse Go source code. They also include, more unusually, a production-quality package to pretty-print Go syntax trees.

These packages in combination form the core of the gofmt tool, but the pretty-printer is worth singling out. Because it can take an arbitrary Go syntax tree and output standard-format, human-readable, correct code, it creates the possibility to build tools that transform the parse tree and output modified but correct and easy-to-read code.

One example is the gofix tool, which automates the rewriting of code to use new language features or updated libraries. Gofix let us make fundamental changes to the language and libraries in the run-up to Go 1.

Inside Google, we have used gofix to make sweeping changes in a huge code repository that would be almost unthinkable in the other languages we use. There's no need any more to support multiple versions of some API; we can use gofix to update the entire company in one operation. It's not just these big tools that these packages enable, of course.

They also make it easy to write more modest programs such as IDE plugins, for instance. All these items build on each other, making the Go environment more productive by automating many tasks.

Test coverage is a term that describes how much of a package's code is exercised by running the package's tests. The program that provides test coverage in Go 1. The usual way to compute test coverage is to instrument the binary. For instance, the GNU gcov program sets breakpoints at branches executed by the binary.

Code coverage

As each branch executes, the breakpoint is cleared and the target statements of the branch are marked as 'covered'. This approach is successful and widely used. An early test coverage tool for Go even worked the same way.

But it has problems. It is difficult to implement, as analysis of the execution of binaries is challenging. It also requires a reliable way of tying the execution trace back to the source code, which can also be difficult, as any user of a source-level debugger can attest. Problems there include inaccurate debugging information and issues such as in-lined functions complicating the analysis. Most important, this approach is very non-portable.

It needs to be done afresh for every architecture, and to some extent for every operating system since debugging support varies greatly from system to system. It does work, though, and for instance if you are a user of gccgo, the gcov tool can give you test coverage information.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.
